The Heart of the Moog - MF-105M Moogerfooger MIDI MuRF is a bank of eight resonant bandpass filters tuned to fixed frequencies. The Animation module is a 24-Pattern sequencer triggering volume envelopes for the eight filters. The Freq Switch toggles between two banks of patterns; 12 bass patterns and 12 mid-range patterns.

Front Panel

PATTERN Rotary Switch: Selects one of 12 Animation Patterns in each bank.

RATE LED: RED = Pattern Clock Rate determined by the Rate control/CV Input, GREEN = Pattern Clock Rate determined by Tap Tempo/Step control and ORANGE = The Current State has been last modified by MIDI and the front panel control knob doesn't indicate the state of the unit.

LEFT/MONO OUT: " Phone Jack carries the summed signal (left+right, all freq. bands) when Right Output is not connected, and carries the Left output signal (Freq. bands: 200 Hz, 450 Hz, 1 KHz, 2.2 KHz) when the right output is connected. Nominal output is '16 dBm to +4 dBm depending on setting of Output Level control when effect is active. Output impedance is 5,000 Ohms.

A MIDI Program change received on the current MIDI Channel with a value 000-023 will override the position of the pattern and Freq Switch. A movement of the Pattern Knob or the Freq Switch sets the MIDI MuRF's current pattern to the one selected by the front panel.

Control Change Messages:

The MIDI MuRF can respond to MIDI CC Messages to alter the settings of the MuRF or the pattern clock rate. Changes made by MIDI CCs are over-ridden by moving the corresponding panel control or changing the state at the corresponding CV input.

Note On Messages:

In MUTE MODE, TRIGGERED MODE and SUSTAINED MODE, MIDI Note On messages can play the MIDI MuRF's filters. In STEP MODE the rate setting is ignored and Note On messages advance the pattern step.

SYSTEM REALTIME:

MIDI_RTC_CLOCK: MIDI CLOCK sets the rate of the pattern clock. When synced to MIDI CLOCK, the RATE LED flashes ORANGE at the Clock division.

MIDI_START: MIDI Clock Start Messages starts the Pattern Clock at the beginning of the Pattern, and synced to the MIDI Clock messages

MIDI_STOP: MIDI Clock Stop Message Stops the Pattern Clock.

MIDI_CONTINUE: MIDI Clock Continue Message restarts a stopped Pattern Clock at the next step in the Pattern.

Defaults to Channel 1 on each power up, unless the stomp switch is closed. If the stomp switch is closed when power is applied then the Pattern Rotary switch sets the current MIDI Channel from 1-12. Changes are stored on power down.
